A monolayer film which includes a crosslinked resin obtained by polymerizing a composition including compound (I) having at least one hydrophilic group selected from anionic hydrophilic groups, cationic hydrophilic groups and hydroxyl groups, and at least one functional group with a polymerizable carbon-carbon double bond wherein the number of the functional groups with a polymerizable carbon-carbon double bond is one when the hydrophilic group is a hydroxyl-containing group; compound (II) having two or more functional groups with a polymerizable carbon-carbon double bond; and at least one compound selected from a surfactant (III) having a hydrophilic moiety including an anionic hydrophilic group, a cationic hydrophilic group or two or more hydroxyl groups, and a hydrophobic moiety including an organic residue, and compound (IV) having a siloxane bond and a molecular weight of 200 to 1,000,000 wherein the surfactant (III) and the compound (IV) have no polymerizable carbon-carbon double bonds. |
